Wisdom teeth extractions are a fairly common procedure. They often cause problems as they are trying to come out. When a wisdom tooth is impacted, it means the tooth is coming in an angle and not straight through the gum line. This can cause moderate to severe pain.
Impacted teeth and wisdom teeth that can potentially cause problems, like infections, need to be removed. Extractions can range from a single tooth, to removing all four wisdom teeth at once. Based on the preference of the doctor and/or the patient, a local anesthetic could be used to numb the areas where the teeth will be extracted. Others will prefer to go under a general anesthetic so that they will be sedated during the procedure. It is highly recomended to have them removed due to the fact that if the tooth is coming in an angle it can cause crowding of the front teeth.
